Posterior reversible encephalopathy syndrome after trigeminal microvascular decompression: A case report

In this case, several postoperative factors likely contributed to the onset of PRES, including acute arterial hypertension, insufficient pain control, and potential manipulation of structures adjacent to the brainstem during surgery. This highlights the multifactorial nature of PRES and the importance of considering it in the differential diagnosis when unexplained neurological symptoms occur after cranial surgery. Increasing awareness of PRES as a possible complication of microvascular decompression may allow for earlier recognition, prompt management, and ultimately improved outcomes for patients undergoing such procedures.
